[TUHS] Re: A few comments on porting the Bourne shell

I was just happy when VR2 came out and found someone had undone all those macros that were in the original code. I hacked Berkeley Job Control as well as command line editing into it (KSH hadn’t seen the light of day outside the labs at that point). I subsequently had a nice talk with Korn at a USENIX. I also sat down with a couple of the guys trying to implement their own shell independent of the ATT code and explained to them how Berkeley job control works. It’s for that reason my name shows up in a lot of the early Linux docs. Amusingly, I’d forgotten all about this stuff until one day I was sitting at a MIPS workstation (MIPS branded, not the DEC spim). Without thinking about it, I typed “fg” at the shell prompt. “Job control not Enabled,” it said. Hey! That sounds like one of my messages. “set -J” I type. “Job control enabled.” Hey! This is a “Ron shell” as it was known at BRL. Turns out it went out on the Mach distros so I’ve found it on all kinds of things like the NeXT etc… ------ Original Message ------ From "Sven Mascheck" <mascheck(a)in-ulm.de> To tuhs(a)tuhs.org Date 12/30/2022 3:20:28 PM Subject [TUHS] Re: A few comments on porting the Bourne shell
